Also, anyone have an idea of how to check humidity other than a hygrometer? (I think that's the right -meter) I'm kinda worried it may be too dry in my room as I'm downstairs& have gas heat. Sometimes when I wake up my lips will be almost dried together!! I have a humidifier tho& it will be on 24/7 starting tomorrow until day 24 or so. (Just in case there r some late hatchers) they'll also be in my closet as the temp stays pretty constant there.
